What's with the yellow urine?

There are many reasons for yellow urine:

1. It's very hot and you sweat a lot. If you drink too little water, your urine will turn yellow.

2. Some diseases can cause yellow urine, such as hepatitis, gallbladder, cholangitis, inflammation, urethritis and so on.

There is a burning sensation when the root is urinating, which is likely to be a frontline or urethral disease.
